  canonicalTransport: Bearer authentication on POST operations; query-key on documented GET compatibility operations.
  compatibility: Existing legacy GET, authentication transports, JSONP or alternate response shapes, HTTP error mappings, and errno values remain operational until measured, announced, and migrated.
  breakingChange: Removing or changing an accepted request transport, operation, response shape, field type, HTTP/application-error mapping, or errno value is a breaking change.
